and sometimes abundant; but more frequent on the coast than inland.
The distribution abroad includes Eastern Siberia and Amurland.
Barred Yellow (Cidaria fulvata).
This very pretty, and most distinct, little species (Plate [65], Figs. 6, 7) does not vary very greatly; there is certainly some modification in the general colour, and in that of the markings, but in both it is only a matter of tint.
The caterpillar is somewhat wrinkled, and in colour is green, with three greyish lines along the back, the central one double; the ring divisions are yellow, and there is a yellow line low-down along the sides. It feeds at night, in May and June, on the leaves of wild rose, and does not object to the garden kinds. (Plate [69], Fig. 3, after Hofmann.)
The moth is out in June and July. It hides by day under leaves in hedges, and although not often induced to get on the wing at that time, the male commences its evening flight at an early hour. It is generally a common species in England and Wales; it occurs here and there through Scotland, up to the Orkneys; and although somewhat local, it is common enough, where found, in Ireland.
Broken-barred Carpet (Cidaria corylata).
The fore wings have an olive-brown basal patch and central band, both are edged with white, wavy lines, and the band is contracted below the middle. (Plate [65], Fig. 9), and often broken at this point (Fig. 10); the inner marginal portion sometimes very small; the space between the basal patch and central band is pale brown, and so also is the outer marginal area; but there are dark clouds and white marks beyond the
white wavy submarginal line. Variable in tint and in marking, the variety generally known as albocrenata, Curtis (Plate [65], Fig. 8), is perhaps most frequent in Perthshire and Sutherland. Two other examples of the Scottish form, which Staudinger has named effusaria, are depicted on Plate [61], Figs. 8, 9.
The caterpillar is green, inclining to yellowish; three stripes on the back, the central one reddish brown and broad, but only distinct at each end, the other paler green; spiracles, white, placed in a reddish-brown stripe, which is sometimes broken up. It feeds on sloe, birch, oak, and the foliage of other trees, and may be found from July to September, and even later.
